Application September 2, 1939, Serial No. 293,285
(Cl. 12S-344) 4 Claims.
My present invention relates to dilators. Y vMore particularly, my invention relates to a type of rectal dilators wherein the muscles of the rectum, and associated tissues, are dilated to a desired degree and, which tissues are, at the same time if desired, given a controlled massage.
Heretofore, it has been the practice in the treatment of many diseases of the rectum to resort to the use of various sizes of so-called rectal dilators which either are made in solid form or, of rigid construction with an opening provided therethrough for the escape of the rectal gases and iiuids er, for the admission of oils, salves etc. The use of such dilators has not been satisfactory because of their construction and, because of the very sensitiveness of the tissues, at the time of treatment, to the use of hard rigid bodies.
Various attempts have also been made to perfect expansible dilators for similar uses but,
because of the types and designs and the cong structions resorted to, such dilators have, in the main, likewise failed to obtain the results desired.
Having the foregoing facts in mind, the present invention was designed to not only overcome these defects but to also, after the desired degree of ination has been obtained, enable the user, or operator, to massage the tissues to a degree prescribed by the disease of the tissues under treatment.
Another object of my invention is the design of a combined dilator and massager of such simple construction and compact design as to permit of ready insertion into the anal canal and rectum; to obtain the desired degree of dilation; to massage the tissues if desired; and to permit of ready cleaning and sterilization after the device is withdrawn.
Having the foregoing objects and advantages in mind, together with the many additional advantages which will be readily apparent to those f skilled in this art, I will now describe in detail a preferred form of my invention and, which is illustrated in the attached drawing, wherein:
Figure 1 is a longitudinal sectional view, partly in elevation;
Figure 2, an end View of the dilator head;
Figure 3, a longitudinal sectional view of a modified form of dilator; and,
Figure 4, a sectional view of another form of dilator head.
In Figures 1 and 2 of the drawing, I illustrate the dilator as comprising generally, a dilator head I, a connecting block or member 2, and an inflation means 3. The dilator head I, has as its main supporting member a cylindrical rod I0 which is provided at one end with a ange I I and a screw threaded portion I2. A tip I3, which may be moulded of hard rubber, Bakelite, or the like, is so shaped as to permit of ready insertion into the anus and rectum. The tip I3 has an internal bore I4 one portion of which is screw threaded for engagement with the screw threaded portion I2 of the rod I0, the other part of the bore being designed to encompass one end of an expansion tube I5, and to force the same into an air-tight joint with the flangev I I. The other end of the rod I0 is likewise screw threaded into a bore I'I in the connection block 2.
The connection block 2 has a reduced portion I8 which terminates in a flange I9 for engagement with the inner end of the expansion tube I5, as will later be described. Screw threads 2i] are provided upon the outer portion of the connection block for the reception of a rectal closing member 2|, which may be made of any suitable material, such as hard rubber, Bakelite or the like. In the drawing I illustrate the bore I'I of the connecting block as extending through the major portion thereof where it communicates with a second bore 22 having a screw threaded portion for the reception of a pipe 23, but it is obvious that the bore I'I could bedrilled completely through the block and the connection with the pipe 23 made at the rear if desired.
In the form illustrated in figures land 3, the expansion tube I5 is provided with a thickened portion and a ange at each end which form a positive seal when the parts are assembled. As before pointed out, when the tip I3 is properly positioned, the outer end of the expansion tube I5 is clamped between the rod III and the tip, and tightly held thereby. At the rear end the tube I5 is securely clamped to the connection block by the rectal closing member 2l.
The expansion tube I5 is arranged to be inflated after being projected into the rectal canal and, is therefore, made of a suitable material such as rubber, or the like. To cause inflation of the tube I5 a bore 24 is provided in the inner end of the rod IIJ which communicates with the interior of the expansion tube at one end and with the bore I'I of the block 2 at the other.
A compression bulb 25, having an inlet valve 2B at one end, is connected to a bleeder valve 21 at the other end and, provides a practical and convenient means for inflating the tube I 5. The bleeder valve 2l is of conventional construction and has an auxiliary check valve 28 which acts to prevent the flow of air when a second compresrectum, a removable expansible tube carried by said reinforcement member, a connecting block secured to one end of said reinforcement member, a bore in said block communicating at one end with the interior of said expansible tube and with an inflation means at the other, a rectal closing member secured to said block, and expansible and compressible means for causing a pulsatory and sliding movement in said tube interposed between said block and said inflation means, said expansible tube being secured at one end to said block and having its free end closed to provide at all times an elongate bearing for longitudinal sliding engagement with the free end of said reinforcement member.
